Hi Mark,

Thanks for your reply Mark, and trying to help me, here is the
symptom: At power up just after the init the protection circuit goes up
and
the power supply LED start to flash red.
I'm sure of my CABASSE speakers as they are working well on my second
AVR-2105.

Hi Mark,

If I've tech qualifications? My got! Yes for sure!
I'm engineer graduated in electronic and my personal lab is fully
equiped from DC up to 40Ghz !
I'm also ham radio operator... F5BQP

This receiver failed for the second time, firstly under warranty two
years ago and just recently!
I send it for repair to DENON, but for the third time I'll put my
noise in it otherwhise it'll cost me more than a bran new one...
DENON sent me the repair quote: 210 Euro and last week I got the
same one on ebay for 270 Euro!...
So now I'll have two rigs and I need to find out the
schematics/drawings for the third time... lol...

Thanks for your post.

My DENON AVR-2105 home cinema receiver failed for the second
time so I would
like to try to repair it myself, as now it's going to cost me
more than a brand new.
Where can I get the service manual with the drawings for this
rig? Many thanks for your help.

Enter "AVR-2105" and "Denon" in the Mfg field. Several manuals
come up, but
not one for the 2105. But maybe you can get some idea from one of
those manuals how to diagnose the problem.

Good luck,

So what is the receiver doing wrong, and have you any technical
qualifications? No disrespect, but people often get in over their
heads on these things.

Mark Z.

Well, you still did not answer my question - what exactly is the
receiver doing wrong?

And since you do possess some qualifications, I could send you the
PDF, though their electronic service manuals aren't the best.

BTW to Malissa. I am an authorized Denon servicer, and pretty well
versed in their surround receivers.


Mark Z.

The most likely cause would be shorted output transistors on one channel.
This is almost always accompanied on Denon's by the emitter resistors
being bad, and often the associated bias transistor. The drivers are
usually OK, but there could be a burned resistor associated with one of
them, such as 4.7 ohms, 10 ohms, etc.

You may e-mail me direct at:

mzacharias@xxxxxxxxxxxxx

and reverse the domain name. I can split the PDF service manual and send
it to you. You'll need WinRAR to re-assemble it.
